Abstract
The invention replaces traditional line and band conductors with sheet conductor, makes the sheet conductor into a gap circular conductor by the methods of punching, tailoring, cutting, eroding, etc, connect many gap circular conductors in a special mode and by the methods of welding, pasting, etc, to form a spiral transformer coil. After applying insulating material, it makes a laminated transformer. The conductor of the transformer is directly exposed on external layer, beneficial to conductor cooling, increasing allowed current density and enhancing power density of transformer and able to reduce the attenuation of skin effect to the allowed current density of conductor.
Description
The invention belongs to electronic technology field.
Transformer is core component in power supply, plays a part transmitted power, isolation and voltage transformation.The temperature rise of transformer is a crucial parameter, traditional transformer be lead in layer on magnetic material, the nexine lead is because the parcel of insulating material and outer layer conductor, it is very difficult to dispel the heat, for the energy operate as normal, have to reduce the current density of lead during design.
The objective of the invention is to manage the direct exposed on external layer of the conductor of transformer, help the conductor heat radiation, increase the permission current density, improve the power density of transformer.
The present invention replaces traditional wire, tape conductor with tabular conductor, with the window section shape of tabular conductor according to magnetic material, consider to be convenient to insulate, to be convenient to factors such as connection, with punching press, cut out, cut, method such as corrosion makes band breach ring-shaped conductor, the breach opposite side of breach one side of a slice and another sheet is coupled together with welding, method such as bonding, form spiral helicine transformer coil.After applying insulating material, make laminated transformer.
The present invention compares with existing transformer coil manufacturing technology, can increase the permission current density of conductor, improves the power density of transformer, and can reduce kelvin effect allows current density to conductor decay.
The applicant thinks that realization best way of the present invention is: use sheet copper to strike out the ring-type copper sheet that has 1 to 2 millimeter breach, for ease of connecting, indentation, there should suitably stretch out, breach one side of a slice and the breach opposite side of another sheet are welded together with kamash alloy, by that analogy, form the spiral helicine transformer coil of certain number of turn.After applying insulating material, make laminated transformer.
Accompanying drawing is depicted as the outline drawing of single lamination when using EC type magnetic material, 1 place's welding lead, and the 2 places welding of 3 places and another sheet so repeats, and forms transformer coil.4 places are used to put into the center pillar of magnetic core.
